Abstract

Control of detachment of the boundary layer around a foil found many applications in various configurations for aircraft the ability to suppress or delay the separation phenomenon leads to enhanced levels of lift, reduce noise and drag. Many studies have been experimentally conducted to test the effectiveness of different actuators. For example, regarding the methods called "active" which introduce external energy into the fluid, it distinguishes the use of movable walls Modi et al. [1], methods based on suction or blowing Wygnanski [2], McCormick [3], acoustic methods Collins [4], thermal Chang [5] or electromagnetic Gad-el-Hak [6]. In recent years, synthetic jets have been used to control flow separation and to stabilize the boundary layer by adding/removing momentum with the formation of vortical structures Wygnanski [7]. More recently, Gilarranz et al. [8] performed a study of flow separation over NACA0015 airfoil with synthetic jets control, but the modification by the control of the boundary layer has not been clearly identify.
